More specifically, we tested whether the degree of linear dependency between SRC and TGFB1 mRNA levels (degree of correlation) is influenced by the abundance of PPARB/D mRNA present in the tumour (the significance of the interaction term TGFB1: PPARB/D of the linear model SRC ∼ TGFB1 + PPARB/D + TGFB1: PPARB/D). This evidence concerns the gene SRC and neoplasm.
